The change pits tradition versus a desire to be a bigger player in world markets. Vermont is the No. 1 maple syrup producer in the United States, but its unique labeling standards put it at odds with the other big producers, including Canada.

The state Senate last week passed and sent to the House a measure to drop fancy, grade A medium amber, dark amber, and grade B. (Fancy is the lightest and mildest, while grade B is the darkest and has the strongest maple flavor.)

In their place would be several types sharing a grade A label, with descriptive phrases following: golden color and delicate taste; amber color and rich taste; dark color and robust taste; very dark color and strong taste.

‘‘We should not be following everyone else in lock step and . . . giving them the ability to try to pretend that syrup made in another state is anywhere near as good as the syrup made in Vermont,’’ he said.

Mullin later said he was mollified by assurances that the changes would be phased in over three years and that producers wouldn’t have to throw out containers already printed with the existing labels.

State Agriculture Secretary Chuck Ross said the changes have largely been pushed by the industry, though the agency has conducted a series of public hearings to address the concerns of the more reluctant producers.

Thanks to improvements in technology and growing interest by landowners, Vermont’s syrup production has roughly doubled in the past decade, to the extent that supply vastly exceeds any demand that would come from a state of about 626,000, Ross said.

‘‘What’s become clear is that the majority of syrup produced in the state of Vermont is sold in national and international markets,’’ Ross said.

Vermont will maintain its distinct branding by labeling its syrup as coming from the state. Connoisseurs will appreciate that Vermont regulations will continue to require boiling sap for longer than is the case elsewhere, producing a slightly denser product, Ross said. But to continue using a separate grading system would lead to consumer confusion, the secretary added.

Doug Bragg, an eighth-generation syrup producer from East Montpelier, said he was taking the potential changes in stride.

‘‘Most of our customers are asking, why do we have to do this? There’s a logic to it, no question about it,’’ Bragg said. ‘‘It’s still annoying though.’’
